ARTHUR SIDNEY PETER-S, 0F MANCHESTER, ENGLAND.

INK OR FLUID RECEPTAGLE.

Application filed September 7, 1912.

To all eff/0m it may @011.00m

Be it lrnown that l, ARTHUR SIDNEY Perrine, a subject of the King of Great Britain, :residing at 53 Camp street, Lower Broughton, Manchester, in the county oi Lailcaster, England, have invented a new and uset'ul Improvement in or Relating to .lult or Fluid Receptacles, of which the following is a specification.

The improvement relates to inl; receptacles wherein is maintained a constant level ot `liuid during use.

I provide a reservoir for the ink having a clear opening at one side or portion of its surface which is capable ot being closed by a plug or cover provided with an opening therein. rIhis plug communicates with a dip chamber formed integrally with the pluo', which chamber extends in a downward direction to within a short distance of the bottom of the reservoir. A horizontal passage from the dip chamber makes communication between the same and the reservoir containing the ink.

The plug and dip chamber may be provided with a rubber' Washer or baud, to eiliect an air tight joint, or be suitably attached to said vessel. The vessel may be conveniently iilled by placing the same with the cap uppermost, and removing the latter, instead o't providing an additional .filling opening, formed in normal conditions with 'an air tight joint, whereby the cap referred to need not be removed except .tor cleaning purposes. It desired, the cap and hood may be mounted separately.

'With reference to the accompanying drawings, Figure l is a side elevation of a reservoir provided with a combined plug and specially provided dip chamber, according to one form o' my invention, said vessel being suitable ior containing ink, and Fig. Q is a sectional view of said plug and dip :.zhamber. Fig. 3 is a front view of Fig. 1, and Fig. a is an under plan view of Fig. 2. Fig. shows the combined parts of Fig. l when the vessel. is in a tilted position.

a is the reservoir to be supplied with ink, b the plug, and c the dip chamber.

In Fig. 'Q and according to my invention the dip chamber c is provided with an eX- tension o1 having a cavity c2 at the under side, leading to the hole or passage 7a in communication with the air space d within the dip chamber c. rlhe lower portion of Specification of Letters Patent.

Patented J une 2, 1914d serial No. 719,093.

said space, up to the level of the top part of the hole 7c, or thereabout, may form the inl; well space; or the wall between the two levels of ink, as in the case of Fie'. 2 be fur nished by the inserted hood.

ln the various figures the plug o is shown provided with a rubber or like band Z for making an air tight joint with the vessel a, when the plug and dip chamber are in position therein. In the present instance, the said plug is shown capable of being pressed into position instead o' being otherwise attached to said vessel o.

In Fig. 2 the part forming the. aperture c or opening in the plug l) is provided, more or less around the inner portion oil the same, with a projecting rim or lip m, as an additional means for preventing the escape ot the ink, such as any which may be at the bottom of the space d, and should the vessel t be tilted, as indicated in Fig. 5. llhe level a', gf, of the ink in the said vessel. t may be such that, on account of the vacuum or partial vacuum above .laid level, the level of the ink for dipping purposes is, it desired, situated at one ott the positions already in dicated, when the tendency will. be for suoli. level to be maintained in the well on the removal of the ink by the insertion. oit' a pen, as is well understood.

In Fig. 2 the positions and :l-orms ot the extension c1, tunnel or cavity c2, and hole 7s therein, have the effect ot' preventing sedi-- ment entering the space d during the use oi" the vessel. It will also be seen that when the vessel a is tilted, the fluid therein will tend to flow around the external parts of t-hc dip chamber c, as well as into the lower part oi the air space rl; so that when the vessel e is further tilted, the iiuid in the said space d will. rise until it closes the inner end of the opening le, while. the cavity portion c1, c2, oi the dip chamber c will project above the altered level oit.' the 'fluid in the vessel a, thus having the eli'ect ot' preventing the i'urther ingress oit' iluid in the space d, and also prevent-ing the fiuid in said space ruiming out through the aperture e on account of the protrusion of' the extension portion c1, c2, described. By reason of the dip chamber c forming the wall between the two levels' of inlr, it .is obvious that the withdrawal of said dip chamber will enable the vessel a, as well as the hood itself, to be efiectually and con* veniently cleaned, when desired.

and the dip Chamber, substantially as herein le Set forth.

In Witness whereof I have hereunto set my hand in presence of two Witnesses.
